  "account": "Gong Zizheng, a renowned figure in China's planetary defence project, passed away at the age of 61 due to illness. A respected government adviser and influential voice in international space debris organizations, Gong succumbed to his illness on Saturday, according to Chinese media. Details regarding his cause of death remain undisclosed. Colleagues at the China Academy of Space Technology remembered Gong as a diligent scientist passionately committed to his work, a kind-hearted individual, and a generous mentor who shared his knowledge freely with younger scholars. A fellow space debris researcher who collaborated with Gong in his latter years expressed deep sorrow upon hearing of his demise. \"I had been aware since October last year that he was gravely ill, yet I never foresaw his untimely passing,\" he lamented. Despite his distinguished position, Gong was characterized as pragmatic, humble, and unassuming. He was first encountered in December 1964, arriving on a folding bike which he had worn out numerous times due to extensive cycling. Gong pursued his academic journey at the National University of Defence Technology in Changsha, earning a physics bachelor's degree in 1986. He later obtained a doctorate in explosion mechanics from the Beijing Institute of Technology a decade later. During his postdoctoral research at the Chinese Academy of Sciences, Gong spent time as a visiting scholar at esteemed institutions such as Caltech and the Carnegie Institution for Science in the United States. He joined the China Academy of Space Technology in 2006, where he spearheaded efforts to safeguard spacecraft from orbital debris. Among his notable contributions was his work on utilizing lasers to mitigate space junk. His team investigated the feasibility of deploying a laser aboard a satellite to repeatedly target debris, gradually altering its trajectory until it descended into the atmosphere. In 2020, Gong advocated for the establishment of a national near-Earth asteroid defense system in China. The nation is currently developing its inaugural planetary defense mission, slated for launch before 2030. The mission aims to impact an asteroid at speeds surpassing Mach 26, sufficient to either modify its orbital path around the sun or cause it to disintegrate. In a final public address, Gong delivered an engaging lecture on China's space program to high school students in Beijing in May 2025, inspiring young minds to pursue their aspirations in cosmic exploration.",
  "summary": "Gong Zizheng, a pioneer of space debris research and a key figure in China’s planned asteroid defence mission, has died at 61. A top government adviser and prominent leader in international space debris organisations, Gong died on Saturday after a battle with illness, according to Chinese media reports. No further details were given. On social media, one of Gong’s colleagues at the China Academy…",
